you can consider a mainland prepaid (china moble) card with IP international call 17950 prefix I think. The call rate is much cheaper tha IDD. This is for call out only. For receiving call, of course give your contact your mainland number so that you do not pay IDD. But some HK MVNO has 飞线 service, cna tkae for reference.
